  • a terminal affected by the incoming PTT voice data is also referred to as a "first terminal.”
  • received PTT voice data can be converted to text data and provided to the first terminal. If the first terminal does not have a display unit, such as a liquid crystal display (LCD), for outputting text messages, the text data can be received and outputted at the second terminal having a display unit.

  • the PTT server 200 transmits the PTT text message to the mobile terminal (S510).
  • the PTT server 200 transmits the PTT text message to the PTT terminal 100 (S511).
  • the PTT server 200 converts the received PTT voice message to a text message (S513), and transmits the PTT text message to the PTT terminal 100 or to the mobile terminal (S514).

  • the PTT terminal 100 determines the current state of the user, and transmits the signal indicating the current state of the user to the PTT server 200, and the PTT server 200 converts the PTT voice message directed to the PTT terminal 100 to a text message, and transmits the PTT text message to the mobile terminal or the PTT terminal 100.
  • the PTT voice message directed to the PTT terminal 100 is converted to a text message at the PTT server 200, and is transmitted to the mobile terminal of the user. Furthermore, the PTT voice message directed to the PTT terminal 100 is stored in the PTT terminal 100 or the server 100, and then the PTT voice message is reported to the user through a speaker, a lamp or the like of the PTT terminal 100.
  • the PTT terminal 100 after the PTT terminal 100 generates the signal indicating that the user is absent, in conference or busy, and transmits it to the PTT server 200, it generates an absence, conference or busy release signal, and transmits it to the PTT server 200 when the PTT terminal receives an absence or conference release setting signal from the user and a call established with any terminal is terminated.
  • the PTT terminal in the PTT system when the PTT terminal in the PTT system is a wireless PTT terminal, it may generate the signal indicating an absence or conference state without receipt of a mobile terminal number from the user.
  • the PTT server may convert the PTT voice message directed to the wireless PTT terminal to a text message, and then transmit it to the wireless PTT terminal.
  • the signal indicating an absence or conference state may include a number of a wireless PTT terminal other than the wireless PTT terminal, a wired PTT terminal or a terminal having a short message output unit according to needs.
  • the PTT system converts the PTT voice message directed to the PTT terminal to a text message, and displays it on a screen of another terminal or the PTT terminal so that the user can immediately check the PTT message without communication interference when he/she is in absence or in conference, or is busy.
